What makes optical illusions so fascinating?

Our brain is an amazing machine when it comes to recognising patterns. It can process thousands of visual signals in a fraction of a second. But sometimes, it can get confused, especially when it's shown an optical illusion. These tricky images take advantage of how our brain processes what we see and can often fool us, even when the answer is right in front of us.

Neuroscience explains this as a tug of war between the parts of the brain responsible for logic and visuals. The visual cortex sends information to the prefrontal cortex-where decisions and judgments happen. That¡¯s when your brain tries to make sense of what it¡¯s seeing, using memory and past experience. But when something unusual pops up, like in a visual puzzle, your brain may struggle to react in time.

Why Optical illusions are more than just fun

Believe it or not, solving puzzles like this IQ test is actually good for your brain. Studies suggest that regularly attempting visual challenges improves your memory, boosts your attention span, and sharpens your thinking. Those who can solve illusions quickly often have high levels of fluid intelligence and strong observational skills.

So, taking a few seconds to crack this brain teaser might say a lot about your mental strength.
